Be it kownthat LULiGH Amms, a citizen of the United States of America,-esidig at Detroit, in the County of 'Wayne and State of Michigan, hameimiented 'eertain new and useful [m rovements in Paper- Feeding Devicesfor W'riters, he., of which the following isa specificetion, referencebeing had therein to the ecc'ompanying drawing&

i`his nvention relates to a feederadapted to deiiver sheets of paper,envelops, mthe like, seram to a typewriter, addreing machine or thelike.

The iventio consists in the atters here- 'uafter set fol-th, and moreparticularly pointed out in the ppended claims.

In the drawings, Fgure 1 is a View in end clevation of a paper feederembodying features of the invention, with &paper guide and its Operatingparts removed, to give clear View of the feedig mechanisn 1.

Fig. 9is a View in detail of a modified form of the guide. Fig. 10 .is a Viewin dctail of a diffe'ent n'onting ofthe guides. F ig. 11 is a View indetal of :L level' ehain pawl.

Refe'ring to the drawings, 1 indicates a substantially rectanglar opentop rock or casing, into which sheets of pa r or the like may be droppedon end. T is may be of thin sheet metal, as herein shown, or of :mylight material and suitable const-ruetion.

.- The bottom o' base 3 of the casing has a longitudinally disposedsubstantially semi crclar groove 4 or depression near each end in eachof which is a horizontal shaft 5, ts real' o'tion; being joumled in anoter bem-ing n'acket 6 and the rear wall of the casing, and its forwardmsupported portiouextending ,to the edge of a transverse slot 8 in thebottom across the cusing adjcent the front wll thereof nt what na-y hestyled. the delvery end of the csng.

I These sha ft s .are p'efeably insh with the face ot the. ca'sng bottomandeachgiorms the co'e of a sgringhelix 9 'Secured conare inturnedindian a d f astene to the shutt, the body of te helix riding on thebottom of the'groove which acts as a guide 'thereion .These heliees 'arepreferabfy of ..jeliees 1 2 each corresponding in pitch' and dispoitionof tnrnsto the adjacent lower coil, are ca'ed by horizontal shafts 13journale& in suitable hearing apertures in the front and back ivalls ofthe casingl near the top thereof, the helices turning in guide tooves 14in the side walls 15 similar to. the

ttom grooves 4, and the shufts being preferably flush with the outerfaces of the walls.

The shafts 5 and 13 are rotatedin uison hy .a spi-ceket chatin 16passing around sp'oeket wheels 17 keyed or Secured to the outer reatshutt ends, idlers 18 directin the cl'ain so that the spockets on eachsi e of the ca tum over toward the center thereof es jndicated by thearrows. A lever 19 pivoted at its inner end on the back of the isslotted to emb'ace one of the stretches of the chain and a yeighted orspring pressed :wl 20the'eon is adapted to engage the ain and nove t oneacl down stroke of the leve'. Stops 21 limit the throw of the level-sso that each stroke rotates the sprockets once, and a spring 22 returnsit to place.

The extended end 23 of the lever is sha ed for a convenient finger pul!retdily reac ed by the operator-'of the machine on which the eeder may-be mounted. A spring pressed pawl 24 holds the chin and s rocketagainst accidental movement, but yie' ds to allow the chuin to move whenengaged by the level'.

The shaft driving mechansm may of course be replaced by suitable gem-s,transverse shfts with bevel pinions or like means, althou h the cho-indrive s prefer able. Similar y, the shofts of the helces mn beonitted,.us n Fig. 5, where the coil en s 25 are turned to form oxialstb slmfts on which .the upertig gers or sprockets m'e into the firstwide turns of the helioesat the rear of the casin which may beconsidered the reoeiving en of the oasng. A par of bars 28 are eachmovably secured on the exterior of the casing in such; manner that a rowof stub ins 29 on each may be brought into parallel spaced relation withthe rear wall of the casing, and thereoy form in eifect guide grooves oneach side of the asing n alinement with the sepa-ated mtal turns of thehelices.

As a preferred form of constrction, the bars are each slidable on a pairof parallel studs 30 on the outside of the easing, springs 31 holdingthem normally projected against the stud heads, and guide bushmgs 32 onthe bars preventing twisting of the bars. Apertures 33 in the sides ofthe casin allow the pins 29 to enter the casing. Ea end of a rock arm 34pivoted on the ratchet or chain lover stud 35 is articnlated by a link35 to a guide bar 28. A stop 36 on the rock arm s so disposed as to beengaged by the chain lever as the letter is nearing the end of its downstroke to Swing the arm and thus draw the bars inwardly so that the pinethereon project into the casing. When the leveris released and' raisedto initial position by its springs, the springs 31 withdraw the guide rpns from the ca The ins 29 on each bar mav be replace by a t web orflange 37 (ig. 10) in which case a slot 38 takes the place of theapertures 33. The rows of pins or the webs are interrupted to clear theupper heliees and the bars are arohed or otherwise disposed to avoid theupper helix groove .tt is evident that these bars mi ht be mounted asindicated in Fig. 10 wheren they are slightl widened or made into wings39 pivoted at t eir forward edges by hinges 40 with spri 41, their rearfree edges being drawn in y thelink and rock arm arrangement used on theother 4 construction.

are in, the wide turns of the sido lelices are' opened inward and thesame turns of the lower or bottom helices are open upward. At the sametime the forward end coils of the helices are so disposed as to allow asheet to dro down through the bottom slot. While olding the loverdepressed the operator drops a sheet of paper into the receiving end ofthe cesing behind the guides, a stroke of the 'l er'upxad down advancesthe sheet one turn of the heliees, another sheet s then dropped in, andso on until the feedes fully charged, there being as many sheets asthere are elix turns.

When needed for the typewriter, a sti-oke 'of the lever moves the sheetat the forward end of the casn over the slot in the base so that t dropstrough as the helioes are turned out of its way. Thus the operator cansupply machine by merely teaching the leveluntil the: feede-r isexhausted, making the dev ce especially valmble for taking dctatodrectly on the t pewriter, or transcrbmg from a telegrapli receiver, orfor other uses where t is mconvenient. to con tmually iterrupt thewriter to replace a sheet.

The feeder may be made dea enough to take any standard sheet, addtionalside hehces being added if necessary to better sup ort the sheet. It mayhe likewise ada-pt ed or cards, envelnps or for manifolding, a set ofthe paper sh ets and interposed cer hons being placed hetween each turn.

The nsepf the s ing Ielix s prefe-able to the sold screw as the lightgage wire which may -be used allows a very lar -e number of sheets to bepacked in a. sma space, while the yieldable spring clips which the coilsconstitute in efect allow for slightfir regularities in the p per.

The propo'tions of the feedemay be varied to such difi'e-ent sizedsheets and any capacity may be obtained by increasing the length of thelelics or conveyers.

Ohvinusly the details of Construction may he varied without departingfrom the spirit of the invention, and I do not limit myself to anyparticular form or a-rangement of parte.

A slield 43 may be Secured to the rezuwall 7 of the casing to cover themechanism.
